Stunning aurora borealis over Canada viewed from space

Can’t wait till NASA makes 4K (or even 8K) video the standard for satellite videos. Storage volumes have dropped way down in price and the taxpayer money in their pockets can pay for higher res in a New York minute.

I suggest not only clicking on the “expand” icon in the lower RH corner as soon as you start the video running; but, then, move a jot to the left and click the gear shape for settings. No need to change resolution; but, you can reduce playback speed and slow down the pan speed. Way cool! I usually run it at 0.5.

    “Physicists describe new type of aurora” (University of Iowa) https://www.eurekalert.org/pub_releases/2021-05/uoi-pdn050621.php
    “In a new study, physicists led by the University of Iowa report a new feature to Earth’s atmospheric light show. Examining video taken nearly two decades ago, the researchers describe multiple instances where a section of the diffuse aurora–the faint, background-like glow accompanying the more vivid light commonly associated with auroras–goes dark, as if scrubbed by a giant blotter. Then, after a short period of time, the blacked-out section suddenly reappears.
    The researchers say the behavior, which they call “diffuse auroral erasers,” has never been mentioned in the scientific literature. The findings appear in the Journal of Geophysical Research Space Physics.” See https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2020JA028805

    “An article published in the journal Nature Communications this week suggests that the natural light show starts when disturbances on the sun pull on Earth’s magnetic field. That creates cosmic undulations known as Alfvén waves that launch electrons at high speeds into Earth’s atmosphere where they create the aurora.”
